Abstract: A battery with a battery management system is capable of charging the battery with recaptured energy from an energy regeneration device. The battery management system charges the battery with the energy regeneration device if the output voltage from the energy regeneration device is larger than the charging voltage of the battery.

Abstract: A lithium battery designed to replace lead-acid battery. The lithium battery has a plurality of battery cells connected in series and a battery management unit. The battery management unit includes a controller, a sensing unit connected to the plurality of battery cells and the controller, a charging control unit connected to the controller, and a discharging control unit connected to the controller. The battery management unit prevents the batteries connected in parallel from mutually charging each other and also prevents the batteries being depleted completely by outputting a low voltage in pulse mode when the battery has low charge.

Abstract: A battery with a plurality of battery cells disposed on a plurality of cell holders. Each battery cell holder holds two battery cells. The plurality of cell holders with the battery cells are enclosed in a battery case and placed inside an external case with a top cover.

Abstract: A containment system (100) includes a housing (106). A battery pack (104) is situated within the housing. One or more ports (114) are disposed along a surface of the housing. An effluent containment pouch (108) is coupled to the surface of the housing. The effluent containment pouch spans the one or more ports. The effluent containment pouch expands when an electrochemical cell (105) experiences a thermal runaway condition, capturing expelled effluent (116).

Abstract: A connector assembly (100,500) includes a plate (101,501) having a body (107,507) and one or more legs (108,109,110,508,509,510) extending distally from the body. The body can define an aperture (112,512). A flexible substrate (102,502) can electrically couple to the legs such that a portion (202,602) of the body extends distally from an edge (203,603) of the flexible substrate. A connector (103,503) is electrically coupled to the flexible substrate, with one or more circuit components (104,105,504,505) electrically coupled between the legs and the connector. The flexible substrate can define a perimeter (201,601) that is complementary in shape to an upper surface (122,522) of a busbar connector (106,506).

Abstract: Disclosed herein is a battery thermal management system for maintaining the temperature of a battery pack in a hybrid vehicle below a maximum operating temperature threshold. The system comprises a battery pack having a plurality of electronically linked cells and a supply air diffuser having a pattern of openings therein for diffusing exhausted air at a substantially uniform flow throughout the battery pack. The system further comprises sensors for monitoring the temperature of at least a portion of the cells, a fan comprising an inlet through which air is drawn in and an outlet in communication with at least the supply air diffuser, for exhausting air into the first diffuser to lower the temperature of the battery pack, and an electronic control unit in communication with the sensors and the fan for controlling operation of the fan based on temperature signals received from the sensors to maintain the temperature of the battery pack below a maximum operating temperature.

Abstract: Disclosed herein is a battery management system for lithium ion batteries capable of determining a battery pack's state of capacity; determining a battery pack's state of charge limits; adjusting for voltage drops and power losses over a battery's internal and/or connector impedances; adjusting the upper and lower voltage limits of a battery pack; and of actively balancing the cells making up the battery pack. In order to achieve this functionality, the battery pack management system includes an electronic control unit, which unit is coupled to module and cell-level circuitry that is designed to measure operating conditions of the battery such as voltage and current at any given time.
